The Zhou family's heir knelt in the pouring rain late at night, pounding on her door again and again. “Nan Xi, I was wrong...” Meanwhile, in the penthouse suite, the head of the Ji family pinned her against the floor-to-ceiling window, kissed her earlobe, and chuckled. “Look, he's just like a dog.”
